I would expect the Golden Open acrylics to work similarly. I used the retarder to get enough working time to print with the acrylic like ink. It sounds like the Golden Open stuff is already slow-drying. The retardant and/or gel medium may also be useful in adjusting the consistency, if it is too runny.
I am not sure exactly what the paper is. It’s made by Arches. It’s left over from someone else’s college art program and, was likely used for pastels. A large range of papers should be workable for this sort of thing. You want something that won’t deform badly when damp and, will absorb ink. There is, of course, actual printmaking paper available for purists.
Note that I got the paper damp between two wet towels before printing on it. That can really help with the ink transfer on toothy papers like that.
